摘要	The latest Ordovician to earliest Silurian graptoliteAvitograptus avitusis important in the biostratigraphy of the Ordovician-Silurian boundary interval. Two additional species ofAvitograptusare described from the sponge-dominated Anji Biota of the Upper Ordovician Wenchang Formation (Metabolograptus persculptusBiozone) of Zhejiang Province, South China. One species,Avitograptus akidomorphusnew species, is new; the other,Avitograptus acanthocystusnew combination, which was previously placed inClimacograptus, is herein assigned toAvitograptus. The former species may represent the ancestral akidograptid because it is identical in thecal form toAkidograptus, but differs in the development of the proximal end. The evolutionary changes fromAvitograptus avitustoAkidograptusandParakidograptusinvolved distal movement of the origins of th1(1)and th1(2), thecal elongation, and greater outward inclination of the thecal walls.
